Stats aren't being counted...

It's been some time now, when I rate dramas/ movies the stats don't change at all. I don't know if it's just me or anyone else had similar problems, but it's something that I noticed and I hope it can be fixed soon. Thank you for your time and effort. (⁠｡⁠･⁠ω⁠･⁠｡⁠)⁠ﾉ⁠♡

Most of the dramas and movies I have watched were older so I don't know what is the cause of it, I have waited first before opening a ticket but more than 5 titles' stats weren't counted. I hope it's because of maintenance like you said. :/
